VALVE.

SPECIFICATION forming part of Letters Patent No. 250,667, dated-December 13, 1881.

Application filed September 20, 1881. (No model.)

all whom it may concern:

Be it known that I, THOMAS KENNEDY, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Valves for Steam-Pipes and other Purposes, of which the following is a specification.

The object of my invention is to provide for the removal and replacing of the valve-seat without disturbing the valve-shell in whatever fixed position it may be, in steam or other connections. My mode of doing this is quite simple, and will be easily understood by the accompanying drawings, which form a part of this specification.

Figure 1 is a transverse vertical section of an ordinary globe-valve containing my invention. Fig. 2 shows in perspective the removable structure I have provided with the valveseat for the object I have hereinbefore named.

A is the valve-shell. B is the middle wall between the inlet and the outlet ports of the valve-shell. G is the aperture through the middle wall of the shell in which the rem'ovw ble structure D, with the valve-seat, is fitted. D is the removable structure containing the, valve-seat; D, the open ports in the same; D the stem fitted to the aperture Gin the wall of the valve shell, D is the valve-seat; Dfithe top of the structure with the valveseat accurately fitted to the valve-shell. This whole structure is fitted so as to drop in easily into the valve-shell, and to be held in place to some extent by E, which is the valve-cap. F is the valve-stein; G, the manual-wheel by which the valve is operated. H is the valve. d shows the point of junction between the valve-seat structure and the middle wall of the valve-shell.

Obviously, when the cap E is taken off my valve-seat structure D can be lifted up out of the valve-shell, in which it is loosely fitted, and

in the shell, and containing within itself a valve-seat, to which the valveis guided by the said cylindrical skeleton-frame.
